Receiver circuit, chip and electronic equipment

The invention relates to a receiver circuit, a chip and electronic equipment, in the receiver circuit, a signal generation module processes a received original signal and outputs a first processing signal and a second processing signal; the delay module delays the first processing signal to obtain a third processing signal, and outputs the third processing signal to the nonlinear processing module; the envelope information extraction module extracts envelope information of the second processing signal and outputs the envelope information to the nonlinear processing module; and the nonlinear processing module suppresses interference signals in the third processing signals according to the envelope information and a preset nonlinear function, and amplifies useful signals in the third processing signals to obtain fourth processing signals. According to the receiver circuit provided by the embodiment of the invention, strong in-band interference signals with unknown frequency can be suppressed, useful signals with smaller amplitude can be amplified, and the performance of the receiver circuit is improved.
